Product Details

Product Overview
The double spring safety valve is suitable for equipment and pipelines with working temperatures ≤ 350 ℃ for steam, air, and other media. When the pressure inside the equipment and pipelines exceeds the allowable value, the valve automatically opens and then fully discharges. When the pressure drops to the specified value, the valve automatically closes to ensure the safe operation of the equipment and pipelines. The dual spring safety valve is suitable for the liquid phase outlet pipe of liquefied petroleum gas with a working temperature of -40~80 ℃. When the pressure difference between the inlet and outlet is 0.5MPa, liquefied petroleum gas can automatically reflux into the tank.
